Thomas Munro a2b0719cc2 Default to dynamic_shared_memory_type=sysv on Solaris. ... POSIX shm_open() can sleep for a long time and fail spuriously because of contention on an internal lock file on Solaris (and presumably illumos). Commit 389869af fixed the main problem with this, namely that we could crash, but it's now clear that "posix" is not a good default. Therefore, choose "sysv" at initdb time on Solaris and illumos. Other choices are still available by editing the postgresql.conf file. Back-patch only to 15, because contention is much less likely further back, and it doesn't seem like a good idea to change this in released branches. This should clear up the failures on build farm animal margay.
